Title: Physics extension

This is just adding an extension, so it shouldn't cause problems elsewhere. I've just done a pull request so others can have a glance over it if they're interested and suggest improvements. Otherwise, I'll merge it in a day or so.

Thanks to @birkenfeld for rewriting this code for IPython >= 0.11.
